描述 Description

The SN65MLVD048 is a quad-channel M-LVDS receiver. This device is designed in full compliance with the TIA/EIA-899 (M-LVDS) standard, which is optimized to operate at signaling rates up to 250 Mbps. Each receiver channel is controlled by a receive enable (RE). When RE = low, the corresponding channel is enabled; when RE = high, the corresponding channel is disabled.
The M-LVDS standard defines two types of receivers, designated as Type-1 and Type-2. Type-1 receivers have thresholds centered about zero with 25 mV of hysteresis to prevent output oscillations with loss of input; Type-2 receivers implement a failsafe by using an offset threshold. Receiver outputs are slew rate controlled to reduce EMI and crosstalk effects associated with large current surges.
The devices are characterized for operation from –40°C to 85°C.
